The Illinois Department of Commerce and Economic Opportunity (DCEO) believes that affordable housing must be energy efficient to be truly affordable. DCEO has led this effort through the Illinois Energy Efficient Affordable Housing Program initiated in 1988. Under this Program, grants are provided to Illinois based non-profit and for-profit housing developers to include energy efficient building practices in the rehab or new construction of affordable housing units.  Average energy savings range from 50% to 75%.

LEAP works with large Illinois clients including manufacturers, hospitals and universities to help manage their energy costs by making cost-effective efficiency improvements. The program involves key decision-makers and focuses on measures that can bring high returns with modest investments.  LEAP identifies best practices in energy management and examines how energy is integrated with management systems.

Provides technical assistance services to businesses, federal, state and local government, public schools, community colleges, public universities and colleges to assist clients who are considering energy efficiency improvements at existing facilities or to enhance baseline design of new facilities.
